Could you please change the title to be less clickbaity? A Nazi rocket... as opposed to communism rockets and god-fearing, democracy rockets? Please.
'Nazi rocket' is from the original title (although for some reason the title here has been subtly changed - from "How a Nazi rocket could have put a Briton in space"). It's also a specific and potentially interesting piece of information, as opposed to 'communism rockets'. It refers to a specific regime, like someone referring to a 'Roman sword'.
The reason for the change is simple. The one misleading term in the title is the word 'Briton'. A Briton is not a British person, but rather an archaic term for a Celtic person who inhabited ancient Britain.
I thought it would be FAR more click-baity to suggest an ancient Celt tried to reach space in a rocket.
